drm/i915: extract i915_gem_shrinker.h from i915_drv.h
It used to be handy that we only had a couple of headers, but over time i915_drv.h has become unwieldy. Extract declarations to a separate header file corresponding to the implementation module, clarifying the modularity of the driver. Ensure the new header is self-contained, and do so with minimal further includes, using forward declarations as needed. Include the new header from i915_drv.h to avoid sprinkling includes all over the place; this can be changed as a follow-up if necessary. No functional changes.
